Microsoft’s Bing search engine maintained momentum in July and gained a bit on both Google and Yahoo.

According to comScore data (Techmeme), as relayed by Piper Jaffray analyst Gene Munster, Google wound up with July search share of 64.7 percent, down from 65 percent in June. Microsoft was up to 8.9 percent in July, up from 8.4 percent in June.

Now these incremental gains don’t signal a huge trend or anything, but they could add up over time. The more important item may be overall search trend growth. Here’s what Munster said:

Bottom line is we view yesterday’s comScore data to represent a potential headwind to Google’s Q3, but note that paid click data will give a more accurate representation of the search marketplace. Google’s total U.S. queries were down 4% m/m and up 21% y/y in July, which is the slowest y/y increase in queries reported by comScore data since 2005. We note that Google’s monthly U.S. query total, as well as the overall U.S. query volume, has trended down m/m for the past three months following all time highs in April.
